In the first phase of this study, we will pilot the intervention to obtain support person feedback in refining the telephone counseling and other study procedures. We will recruit 30 nonsmoking adult support persons for the pilot to complete the 3-session telephone counseling intervention. Assessments will be completed by mail at baseline and week 4. In phase 2, after refining the intervention, we will use a randomized, two-group design to examine the effect of a 3-session telephone-based intervention versus a self-help intervention (written materials) for nonsmoking adult support persons on increasing their smokers? utilization of the ClearWay Minnesota funded QUITPLAN Helpline. Repeated mailed assessments will be completed by support persons at baseline (week 0) and follow-up at weeks 4 and 26. This study, funded by ClearWay Minnesota, addresses their funding priority area to ?Increase the Availability and Use of Individual Cessation Services.? The Primary Aims of phase 2 are (1) To determine if providing the telephone-based intervention for nonsmoking adult support persons results in a greater proportion of their smokers who call the QUITPLAN Helpline compared to the self-help intervention over the 26 week study period; and (2) To compare treatment groups on change in supportive behaviors provided (Support Provided Measure score) from baseline to week 4. Secondary Aims are to compare the smoker's readiness to quit and utilization of cessation service in the two groups.
